Answer:
h'(x) = -10x + 20
Step-by-step explanation:
To get the derivative of 
, simply use the following formula:
We have the function, h(x) = -5x^2 + 20x
Using the formula, we get the derivative to be:
-10x + 20
so h'(x) = -10x + 20
Answer:
Step-by-step explanation:
P=R3000.00
T=3 years
SI=R905
SI=P\times R\times T\\R905=R3000\times \frac{r}{100}\times 3SI=P×R×T
R905=R3000×

Answer:
Sara picked 48 peaches.
Step-by-step explanation:
Sara originally had 39 peaches, but after picking more, she had 87 peaches.
If x is the number of peaches she picked, then:
x + 39 = 87
x = 48 peaches
Answer:
__2_sides of equal length
__2_acute angels
__0_right angle(s)
_1__obtuse angle
The triangle is _isosceles____and_obtuse____.
Step-by-step explanation:
if this is the right triangle the longest side will be √162≈ 12.7
the longest side is 15 so the vertex angle is obtuse
